jQuery unserialize Form plugin

gistfile1.js

// Unserialize (to) form plugin - by Christopher Thielen
// adapted and desuckified (a little) by Paul Irish

// takes a GET-serialized string, e.g. first=5&second=3&a=b and sets input tags (e.g. input name="first") to their values (e.g. 5)


(function($) {
    $.fn.unserializeForm = function(values) {

        if (!values) {
            return this;
        }

        values = values.split("&");

        var serialized_values = [];
        $.each(values, function() {
            var properties = this.split("=");

            if ((typeof properties[0] != 'undefined') && (typeof properties[1] != 'undefined')) {
                serialized_values[properties[0].replace(/\+/g, " ")] = properties[1].replace(/\+/g, " ");
            }
        });

        values = serialized_values;

        $(this).find(":input").removeAttr('checked').each(function() {
            var tag_name = $(this).attr("name");
            if (values[tag_name] !== undefined) {
                if ($(this).attr("type") == "checkbox") {
                    $(this).attr("checked", "checked");
                } else {
                    $(this).val(values[tag_name]);
                }
            }
        })
    }
})(jQuery);

Works nicely for me.
you're missing semicolons in line 37 + 38

quick hack, because my form had radio-buttons - certainly not the best method - but it works for me
else if ($(this).attr("type") == "radio") { $('input:radio[name="'+tag_name+'"][value="'+values[tag_name]+'"]').attr("checked",true); }

There is a problem with special charachters that doesn't get really "unserialized", for example '@'
What is did is changed line 34 to this:
$(this).val( decodeURIComponent(values[tag_name]) );
